Description
Technical field
The present invention relates to a kind of reverse-flow type transition joint, being specifically related to one can enter trace impurity and unrelated mixture
The fluid connection that row filters.
Background technology
In the fluid device the highest to water quality requirement; drum, distiller and some chemical industry equipments in such as boiler; not only it is frequently necessary to water is filtered; and these equipment are because bigger operational difference and soda acid change; often produce incrustation scale; especially at pipe joint, being particularly easy to because fouling or foul alluvial block, either impurity still blocks and all can bring certain potential safety hazard to these stress reaction equipment；
So, in the joint of these equipment higher to water quality requirement, needing to arrange some both can have filter effect, ensured certain fluid filter assemblies by property again simultaneously；
Wherein ZL201320354014.4 proposes a kind of filter pipeline joint, and this kind of joint working condition requirement to using can be higher, and this joint realizes the filtration to fluids within pipes by an easy replaceable filter assemblies；Although the particle being relatively large in diameter or sheet impurity can be filtered by cellular joint; but the flow resistance that cellular flowing hole road brings can be the highest; can seriously reduce the flow of current; this kind of poroid flowing hole road is easy to or flowing hole road internal incrustation excessive because of particle and blocks simultaneously; once block, associated vessel internal pressure can be caused too high, explode; and the bearing capacity of this kind of transition joint is the biggest, it is easy to leak；
ZL201320158107.X discloses the spiral-flow filter of another kind of tank body shape, this structure employing fluid eddy flow is centrifugal carries out filtering flow, flow resistance ratio is relatively low, but the volume ratio of this structure is huger, cannot realize minimizing even interface, and this structure also has certain requirement to the approach axis of fluid, so general expenditure ratio is relatively low, cost is the highest, is not suitable for the pipeline configuration to some closenesses are high and filters；
To sum up, there are the following problems for existing filter device for pipes or transition joint:
1, flow resistance is relatively big, and being easily caused pressure vessel cannot row pressure in time；
2, filtration is relatively backward, and the poroid filtration of traditional iris type is affected bigger by profile and the size of impurity in fluid；
3, it is very easy to because fouling and filtration particle block relatively greatly；
4, efficient filtration often volume ratio is huger, it is impossible to realize miniaturization and densification is arranged.
